SPECIFICATION FOR GLOVES, WOOL, KNITTED ( Second Revision ) 0. FOREWORD 0.1 This Indian Standard ( Second Revision ) was adopted by the Indian Standards Institution on 14 March 1986, after the draft finalized by the Hosiery Sectional Committee had been approved by the Textile Division Council. 0.2 This standard originally published in 1969 was revised in 1976. second revision has been taken up to: The a) incorporate single thread breaking load for all wool and wool nylon blend yarn, b) substitute size number 0 to 4 for 1 to 5 as these size numbers are used by Defence and other paramilitary forces, c) specify courses per dm, d) specify colour fastness rating in respect of both change in colour and staining of adjacent fabric for colour fastness to washing and perspiration, and e) delete the requirement of water soluble chromium. 0.3 For the purpose of deciding whether standard is complied with, the final expressing the result of a test or analysis, ance with IS : 2-1960".

CONDITIONING ATMOSPHERIC OF TEST OF TEST SPECIMENS AND CONDITIONS FOR TESTING A-l.1 The test specimens shall preferably be conditioned for testing and tested in the standard atmosphere as given in IS : 6359-1979". A-2. DIMENSIONS A-2.1 Take a glove from the test sample. Lay it flat on a horizontal surface. Remove all creases and wrinkles without distorting it. Measure correct to the nearest millimetre the dimensions given in Table 1. *Method for condirioning of textiles. 11 IS : 5459 - 1986 A-3. MASS A-3.1 Take a set of 10 pairs of gloves from the test sample. Condition them to moisture equilibrium for 24 hours ( see A-l.1 ) and weigh to an accuracy of 10 g. A-4. WALES A-4.1 Take a glove constituting the test sample. Lay it flat on a horizontal surface. Remove all creases and wrinkles without distorting it. Count with the help of a pick glass or magnifying glass, the number of wales per decimetre at the required portion of the glove. A-5. COURSES A-5.1 Take a glove constituting the test sample. Lay it flat on a horizontal surface. Remove all creases and wrinkles without distorting it. Count with the help of a pick glass or magnifying glass, the number of courses per decimetre. A-6. DIMENSIONAL CHANGE ( DUE TO RELAXATION ) A-6.1 Marking of Test Specimens - Take a glove from the test sample. Mark centrally on it by means of indelible ink or a fast dyed cotton sewing thread an area 15 X 15 cm with two of its sides running in the direction of wales and the other two in the direction of courses. Spread this test specimen on a flat smooth surface, carefully removing by hand all creases and wrinkles. Within this area, mark six pairs of marks, three pairs each in the direction of wales and courses in such a way that the distance between each pair of marks-is the same. A-6.2 Procedure A-6.2.1 Place test specimen on a glass plate and carefully remove by hand all creases and wrinkles without stretching the test specimen and place another glass plate on the test specimen. Measure correct to the nearest millimetre the distance between each pair of marks separately. A-6.2.2 Lay the test specimen flat in a tray of suitable size and soak the specimen under a head of 25 mm of water containing 0.5 percent Drain out the suitable wetting agent at room temperature for 2 hours. water and remove the test specimen carefully so that it is not stretched. Lay the specimen flat on a smooth surface. Remove the excess water with the help of an absorbent material or by keeping the smooth surface in a sloping position. Dry the specimen at room temperature. NOTE - Removal of excess water hy wringing the test specimen is not permitted. A-6.2.3 Proceed as in A-6.2.1 and measure correct to the nearest millimetre the distance between each pair of marks separately. Preserve the specimen for A-7.1.1 for determining felting shrinkage. 12 IS : 5450 - 1986 A-6.3 Calculation A-6.3.1 Calculate separately the percentage of dimensional change for each pair of marks in the directions of wales and courses by the follow~ing formula: Dimensional percent where a = the distance between a pair of marks ( along the wales or courses as the case may be ) before soaking, and change ( due to relaxation ), =Ua b x100 b = the distance soaking. between the same pair of marks after A-6.3.2 Determine the average tion ), percent in each direction.

Soak it under a head of 25 mm of water containing 0.5 percent suitable wetting agent at 30 to 35°C for overnight. Drain out the water and remove excess water from the test specimen by passing through rubber wringers or using hydroextractor so that the water retained is about 60 percent of air-dry mass of specimen. A-7.1.2 Evenly wet the specimen with 5 percent soap solution corresponding to 25 percent air-dry mass of the specimen. This is conveniently done by spraying it with soap solution by means of a pipette or burette. Subject the specimen to 2 000 blows at the rate of 70 blows per minute in a suitable single hammer milling machine ( see Note ), taking care that those portions of the specimen received initial hammering which are least exposed to severe milling during actual use. Wash the specimen in Dry and condition it to moisture equilibrium at room distilled water. temperature. Measure the distance between the different pairs of marks as in A-6.2.1. machine should be about NOTE - The air-dry mass of a charge for the milling sufficient quantity of entirely unfeltable woollen knitted goods r70 g. Accordingly, may be added to form a charge. 13 IS : 9490 - 1986 A-7.2 Calculation A-7.2.1 Calculate separately the percentage ( due to felting ) for each pair of marks in the courses by the following formula: St =-c where sr = dimensional change ( due to felting ), percent; b b x 100 of dimensional change direction of wales and b = the distance between a pair of marks ( along the wales and courses as the case may be ) before milling as measured in A-6.2.3; and c = the distance A-7.1.2. A-7.2.2 Calculate each direction. A-8. SCOURING between the same pair of marks as noted in the average dimensional change ( due to felting ) in LOSS Cut the test specimen weighing about 10 g A-8.1 Test Specimen from each sample. A-8.2 Procedure A-8.2.1 Dry the test specimen to constant mass in the drying oven at 105 f 3°C temperature and determine its mass accurately. NOTE Constant mass shall be deemed to have been reached if the difference between the tw-o successive weighings at an interval of 20 minutes is less than 0'05 percent. A-8.2.2 Extract the above specimen with a mixture of benzene and methyl alcohol in the proportion of 3 : 2 in a Soxhlet apparatus for 4 hours at the rate of 5 extractions per hour, by placing the specimen in a thimble and covering it with cotton or wool previously extracted with The solvent the above stated mixture of benzene and methyl alcohol. Dry the residue to a constant shall then be distilled off from the extract. mass ( see Note under A-8.2.1 ) at 105 f 3°C and determine the mass accurately. 14 IS:5450A-8.3 Calculation - 1986 following Calculate the scouring loss by the formula: Scouring where a = mass of the dry residue b = mass of the test specimen loss, percent = + x 100 ( see A-8.2.2 ( see A-8.2.1 ), and ). 15
